  • Test Planning for Core-based Integrated Circuits under Power Constraints
    • Authors: Breeta SenGupta; Dimitar Nikolov; Urban Ingelsson; Erik Larsson
      Pages: 7 - 23
      Abstract: Abstract This paper addresses reduction of test cost for core-based non-stacked integrated circuits (ICs) and stacked integrated circuits (SICs) by test planning, under power constraint. Test planning involves co-optimization of cost associated with test time and test hardware. Test architecture is considered compliant with IEEE 1149.1 standard. A cost model is presented for calculating the cost of any test plan for a given non-stacked IC and a SIC. An algorithm is proposed for minimizing the cost. Experiments are performed with several ITC’02 benchmark circuits to compare the efficiency of the proposed power constrained test planning algorithm against near optimal results obtained with Simulated Annealing. Results validate test cost obtained by the proposed algorithm are very close to those obtained with Simulated Annealing, at significantly lower computation time.

  • A HW/SW Cross-Layer Approach for Determining Application-Redundant
           Hardware Faults in Embedded Systems
    • Authors: Christian Bartsch; Carlos Villarraga; Dominik Stoffel; Wolfgang Kunz
      Pages: 77 - 92
      Abstract: Abstract Hardware devices of recent technology nodes are intrinsically more susceptible to faults than previous devices. This demands further improvements of error detection methods. However, any attempt to cover all errors for all theoretically possible scenarios that a system might be used in can easily lead to excessive costs. Instead, an application-dependent approach should be taken, i.e., strategies for test and error resilience must target only those errors that can actually have an effect in the situations in which the hardware is being used. In this paper, we propose a method to inject faults into hardware (HW) and to formally analyze their effects on the software (SW) behavior. We describe how this analysis can be implemented based on a recently proposed HW-dependent software model called program netlist (PN). We show how program netlists can be extended to formally model the behavior of a program in the event of one or more hardware faults. Then, it is demonstrated how the results of the PN-based analysis can be exploited by a standard ATPG tool to determine hardware faults at the gate level that are “application-redundant”. Our experimental results show the feasibility of the proposed approach.

  • Fast and Automated Electromigration Analysis for CMOS RF PA Design
    • Authors: Junjie Gu; Haipeng Fu; Weicong Na; Qijun Zhang; Jianguo Ma
      Pages: 133 - 140
      Abstract: Abstract This paper presents fast and automated electromigration (EM) reliability modeling by using automated modeling generation (AMG) algorithm. The AMG converts human based EM modeling into an automated modeling and simulation process with the help of ANSYS parametric design language (APDL) program. For automating the neural model training process, training-driven adaptive sampling is applied to integrate data generation, data distributions determination, model structure adaptation, training and testing into a unified framework. Fully automated reliability model construction and simulation is achieved for the first time. This method effectively shortens the period of EM modeling by using dynamic sampling method. Furthermore, the heat generation from active devices has been considered to describe the heat effect on the interconnect reliability. Through the proposed technique, the allowable sizes, temperature and output power of a CMOS radio frequency power amplifier (RF PA) are derived to give reliability criteria for PA designer.

  • A Passive Authentication System Based on Optical Variable
           Nano/Micro-Structures
    • Authors: Jasbir N. Patel; Hao Jiang; Bozena Kaminska
      Abstract: Abstract A new optical authentication and security system using optical variable nano/micro-structures (OVNs) is presented. The proposed design features a passive authentication method using a simple optical system found in common fabrication facilities. The passive authentication is obtained by insertion of an OVN image directly on a processing layer or divided between multiple layers of the fabrication process. Authentic fabrication process is validated when the proper alignment (reconstructed image, for example) at the end of the fabrication is achieved. Simple proof-of-concept devices with the OVN-based authentication system are presented along with the optical images of the resulting authentication patterns.

  • Total Ionizing Dose Effect and Single Event Burnout of VDMOS with
           Different Inter Layer Dielectric and Passivation
    • Authors: Jiongjiong Mo; Hua Chen; Liping Wang; Faxin Yu
      Abstract: Abstract In this paper, Total Ionizing Dose (TID) and Single Event Burnout (SEB) effects are investigated on self-developed power VDMOS devices with breakdown voltage (BV) of 200 V. Different inter layer dielectrics (ILD) including Borophosphosilicate glass (BPSG) and Si3N4, and different passivation layers including Si3N4 and SiO2 are tested to evaluate their radiation hardness. The TID results indicate that the threshold voltage VTH of VDMOS is negatively shifted after radiation, and can barely be recovered by post TID annealing. As an ILD layer, Si3N4 is proved to be better than BPSG with less VTH shift. Passivation layer can also influence the TID hardness, which increases with the layer thickness. Heavy ion radiation tests indicate that the devices with different ILD and passivation designs can barely influence the SEB effects. All tested devices with normal breakdown voltage of 200 V cannot survive at VDS more than 80 V under heavy ion radiation.

  • ADC Spectral Testing with Signal Amplitude Drift and Simultaneous
           Non-coherent Sampling
    • Authors: Yuming Zhuang; Degang Chen
      Abstract: Abstract Spectral testing is a vital category in modern measurement industry. The challenge is to cost-effectively test the ADCs accurately. Among many test requirements, maintaining input test signal stability and achieving coherent sampling are one of the bottlenecks for accurate testing of the ADC. If these stringent test requirements are not met, accurate spectral test results of the ADC cannot be obtained. This paper presents a method that simultaneously relaxes the requirements of precise control over source amplitude, and of the need for coherent sampling. By dividing the output data into segments, accurate estimation of the drift fundamental in each segment can be obtained, by removing the estimated drift fundamental and replacing with a coherent, non-drift fundamental in time domain, accurate spectral results can be achieved. Extensive simulation results have validated the accuracy and robustness of the proposed method. Furthermore, measurement results have verified the proposed method by accurately obtain spectral results of the ADC under test.

  • A Low-Cost Reliability vs. Cost Trade-Off Methodology to Selectively
           Harden Logic Circuits
    • Authors: I. Wali; B. Deveautour; Arnaud Virazel; A. Bosio; P. Girard; M. Sonza Reorda
      Abstract: Abstract Selecting the ideal trade-off between reliability and cost associated with a fault tolerant architecture generally involves an extensive design space exploration. Employing state-of-the-art reliability estimation methods makes this exploration un-scalable with the design complexity. In this paper we introduce a low-cost reliability analysis methodology that helps taking this key decision with less computational effort and orders of magnitude faster. Based on this methodology we also propose a selective hardening technique using a hybrid fault tolerant architecture that allows meeting the soft-error rate constraints within a given design cost-budget and vice versa. Our experimental validation shows that the methodology offers huge gain (1200 ×) in terms of computational effort in comparison with fault injection-based reliability estimation method and produces results within acceptable error limits.

  • Radiation-Induced Fault Simulation of SOI/SOS CMOS LSI’s Using Universal
           Rad-SPICE MOSFET Model
    • Authors: Konstantin O. Petrosyants; Lev M. Sambursky; Igor A. Kharitonov; Boris G. Lvov
      Abstract: Abstract The methodology of modeling and simulation of environmentally induced faults in radiation hardened SOI/SOS CMOS IC’s is presented. It is realized at three levels: CMOS devices – typical analog or digital circuit fragments – complete IC’s. For this purpose, a universal compact SOI/SOS MOSFET model for SPICE simulation software with account for TID, dose rate and single event effects is developed. The model parameters extraction procedure is described in great depth taking into consideration radiation effects and peculiarities of novel radiation-hardened (RH) SOI/SOS MOS structures. Examples of radiation-induced fault simulation in analog and digital SOI/SOS CMOS LSI’s are presented for different types of radiation influence. The simulation results show the difference with experimental data not larger than 10–20% for all types of radiation.

  • A High-Level Approach to Analyze the Effects of Soft Errors on Lossless
           Compression Algorithms
    • Authors: Serhiy Avramenko; Matteo Sonza Reorda; Massimo Violante; Görschwin Fey
      Abstract: Abstract In space applications, the data logging sub-system often requires compression to cope with large amounts of data as well as with limited storage and communication capabilities. The usage of Commercial off-the-Shelf (COTS) hardware components is becoming more common, since they are particularly suitable to meet high performance requirements and also to cut the cost with respect to space qualified ones. On the other side, given the characteristics of the space environment, the usage of COTS components makes radiation-induced soft errors highly probable. The purpose of this work is to analyze a set of lossless compression algorithms in order to compare their robustness against soft errors. The proposed approach works on the unhardened version of the programs, aiming to estimate their intrinsic robustness. The main contribution of the work lies in the investigation of the possibility of performing an early comparison between different compression algorithms at a high level, by only considering their data structures (corresponding to program variables). This approach is virtually agnostic of the downstream implementation details. This means that the proposed approach aims to perform a comparison (in terms of robustness against soft errors) between the considered programs before the final computing platform is defined. The results of the high-level analysis can also be used to collect useful information to optimize the hardening phase. Experimental results based on the OpenRISC processor are reported. They suggest that when properly adopted, the proposed approach makes it possible to perform a comparison between a set of compression algorithms, even with a very limited knowledge of the target computing system.

  • On the Consolidation of Mixed Criticalities Applications on Multicore
           Architectures
    • Authors: Stefano Esposito; Massimo Violante
      Abstract: Abstract In this paper we propose a hybrid solution to ensure results correctness when deploying several applications with different safety requirements on a single multi-core-based system. The proposed solution is based on lightweight hardware redundancy, implemented using smart watchdogs and voter logic, combined with software redundancy. Two techniques of software redundancy are used: the first one is software temporal triple modular redundancy, used for those tasks with low criticality and no real-time requirement. The second software redundancy technique is triple module redundancy for tasks with high criticality and real-time requirements, assisted by a hardware voter. A hypervisor is used to separate each task in the system in an independent resource partition, thus ensuring that no functional interference is occurring. The proposed solution has been evaluated through hardware and software fault injection on two hardware platforms, featuring a dual-core processor and a quad-core processor respectively. Results show a high fault tolerance achieved using the proposed architecture.

  • High Speed Energy Efficient Static Segment Adder for Approximate Computing
           Applications
    • Authors: R . Jothin; C. Vasanthanayaki
      Abstract: Abstract Real time high quantity digital data computing design needs to achieve high performance with required accuracy range. The constraints involved with high performance are low power consumption, area efficiency and high speed. This paper proposes a design of high speed energy efficient Static Segment Adder (SSA), which improves the overall performance based on static segmentation. Accuracy Adjustment Logic (AAL) is incorporated to improve the accuracy derived from negating lower order bytes of input operands. In this paper, an integration of static segment method and accuracy adjustment logic is used to achieve computational accuracy for error tolerant applications. The proposed adder design enables to provide high speed and energy efficiency through the static segmentation method. Image enhancement operation is carried out using proposed SSA design. In this method, 99.4% overall computational accuracy for 16-bit addition even with 8-bit adder can be achieved.

  • Golden-Free Hardware Trojan Detection with High Sensitivity Under Process
           Noise
    • Authors: Tamzidul Hoque; Seetharam Narasimhan; Xinmu Wang; Sanchita Mal-Sarkar; Swarup Bhunia
      Abstract: Abstract Malicious modification of integrated circuits in untrusted design house or foundry has emerged as a major security threat. Such modifications, popularly referred to as Hardware Trojans, are difficult to detect during manufacturing test. Sequential hardware Trojans, usually triggered by a sequence of rare events, represent a common and deadly form of Trojans that can be extremely hard to detect using logic testing approaches. Side-channel analysis has emerged as an effective approach for detection of hardware Trojans. However, existing side-channel approaches suffer from increasing process variations, which largely reduce the detection sensitivity and sets a lower limit of the sizes of Trojans detectable. In this paper, we present TeSR, a Temporal Self-Referencing approach that compares the current signature of a chip at two different time windows to isolate the Trojan effect. Since it uses a chip as a reference to itself, the method completely eliminates the effect of process noise and other design marginalities (e.g. capacitive coupling), thus providing high detection sensitivity for Trojans of varying size. Furthermore, unlike most of the existing approaches, TeSR does not require a golden reference chip instance, which may impose a major limitation. Associated test generation, test application, and signature comparison approaches aimed at maximizing Trojan detection sensitivity are also presented. Simulation results for three complex sequential designs and three representative sequential Trojan circuits demonstrate the effectiveness of the approach under large inter- and intra-die process variations. The approach is also validated with current measurement results from several Xilinx Virtex-II FPGA chips.

  • An ATE Filter Characterization ToolKit Using a Discrete Chirped Excitation
           Signal as Stimulus
    • Authors: Peter Sarson
      Abstract: Abstract This paper describes how to measure a full suite of RF filter characteristics using reusable code to produce a chirp that sweeps the filters’ frequency range. It shows how to measure 3 dB points, bandwidth and group delay of any filter and how accurately the technique correlates to measurements of the silicon performance made in the lab. The test time saving and stability of results are shown as well as the advantages of the technique with regard to having full characterization data available in a production program. Historically test engineers have been asked to characterize certain parts of the device during debug of initial silicon. This adds time pressure to an already time critical sections of product delivery milestone because device characterization on ATE is never part of the original test quotation. This also adds considerable cost pressure since this takes extra software development and tester time to produce. The proposed method can alleviate a part of this problem.

  • An Efficient Reverse Engineering Hardware Trojan Detector Using Histogram
           of Oriented Gradients
    • Authors: Abdurrahman A. Nasr; Mohamed Z. Abdulmageed
      Abstract: Abstract The problem of hardware Trojan is certainly serious, complex and tricky. Therefore, hardware Trojan (HT) detection is difficult, time and effort consuming and challenging due to non-trivial threats that compromise the security of integrated circuits (IC). The problem becomes more serious with the extensive outsourcing of ICs design and fabrication by untrusted foundries. Recently, hardware Trojan detection has gained insight and interest from different researches and industries in order to detect Trojan horses in the fabrication phase of an IC. In that phase HT detection requires expensive testing techniques. Hardware Trojans in the fabrication phase show that the detection process may be either side-channel based (non-destructive) or reverse engineering based (destructive). The destructive approach consists mainly of three steps: (1) decapsulation, (2) delayering and (3) imaging for layout identification. This paper presents a new approach for automating the third step, namely, the layout identification of the underlying circuit. The proposed approach automatically extracts and describes the features of circuit layout by making use of histogram of oriented gradient. Features descriptors obtained from such histogram of oriented gradient are then fed to a machine learning classifier represented by a decision tree that aims at learning the pattern of malicious ICs in order to differentiate them from benign ones. In addition, the classification result is enhanced by utilizing AdaBoost learning algorithm to produce a strong meta-classifier in a chain of cascaded stages. Based on that scheme, a composite classification model is built up to provide an Automatic Hardware Trojan Detection and description Tool (AHTDT). The proposed model has been tested (on noisy and clean data) and evaluated using ISCAS89 benchmark dataset. Such benchmark is emphasized deliberately to show different Trojan examples –namely, Trojan insertion, Trojan deletion and Trojan parametric- inside hardware circuits. Model simulation and evaluation results have shown a remarkable enhancement in HT detection compared to other reverse engineering detection techniques. Moreover, the proposed approach has the advantages of being automatic, systematic and capable of detecting and diagnosing hardware Trojans accurately with high detection rate, while keeping low false positive rate.

  • Using Distortion Shaping Technique to Equalize ADC THD Performance Between
           ATEs
    • Authors: Peter Sarson; Haruo Kobayashi
      Abstract: Abstract In this paper, we describe how a phase switching technique is used to control the harmonic contents of a generated sinusoidal signal using digital signal processing techniques. We will describe how this technique equalizes the harmonic performance of arbitrary waveform generators installed in a large scale integration test system, allowing extended performance testing of the total harmonic distortion of an analog-to-digital converter that ordinarily would be possible only using more advanced test equipment. Once a device has been characterized and correlated to the bench, a test engineer is required to release the product into production. One of the major issues surrounding this exercise is the difference in the obtained results between testers of the same manufacture for parameters sensitive to harmonics, noise, and spurious components such as total harmonic distortion. By using the techniques developed in this paper, the user will be able to deploy an academic solution to an industrial problem and extend the range of test equipment that ordinarily would need to be discarded for such test requirements. We will then show the gauge repeatability and reproducibility between two testers of the same manufacture, and how using the described technique produces a better correlation, thus allowing less stringent guard-bands to guarantee the performance of those devices that have performance criteria close to the device specification. This work also goes some way to proving previous papers’ works on distortion shaping testing to enhance the spectral performance of arbitrary waveform generators.

  • Four-Port Network Parameters Extraction Method for Partially Depleted SOI
           with Body-Contact Structure
    • Authors: Jun Liu; Yu Ping Huang; Kai Lu
      Abstract: Abstract This work presents a model parameter extraction method based on four-port network for RF SOI MOSFET modeling. The gate, drain, source and body terminals are served as four separate ports. Four-port measurement simplifies the determination of small-signal equivalent circuit model elements such as parameters related to the body terminal which become clear in the equivalent circuit analysis. The extraction method of the RF SOI MOSFET extrinsic parasitic elements was also presented. The accuracy of the model extraction was verified by measurement and simulation from 100 MHz to 20 GHz.
